    190190Depending on the requestData masked value, we will have a {{{MgFeatureInformation}}} (containing the tooltip, hyperlink and selection set), a {{{MgBatchPropertyCollection}}} containing the selected feature attributes and a {{{STRING}}} (containing the base64 selection image). Then we construct the appropriate XML response based on what pieces of data we have.

    238302For Fusion, it gets a bit more complicated as it makes various calls to assorted PHP scripts (SaveSelection.php, GetSelectionProperties.php, etc). This asynchronous call chain of PHP scripts needs to be refactored so that it only needs to send the new QUERYMAPFEATURES request and process its response as it does all the things that these PHP scripts were previously needed for. In addition, it's client-side selection structure is radically different from that of the AJAX viewer. Given the very early stage of this RFC, discussion with Fusion developers is needed to determine if the sample responses proposed here is enough to replicate the existing client-side selection model and this RFC will be updated accordingly based on developer feedback.
    239303
     304With these modifications in place, the AJAX Viewer request chain for a single selection looks like this:
     305
     306[[Image(AjaxViewerAfter.PNG)]]
     307
     308And the Fusion Viewer request chain for a single selection looks like this:
     309
     310[[Image(FusionAfter.PNG)]]
     311
     312The last request is a GETDYNAMICOVERLAYIMAGE request. The reason we cannot currently eliminate the sending of this 3rd request is because the OpenLayers.Layer.MapGuide class is yet not aware of the changes in this RFC.
     313
     314Modifying OpenLayers.Layer.MapGuide to accept an inline selection image data URI will eliminate the need for this 3rd request.
     315
     316Similarly, the request to SaveSelection.php may not even be needed either as QUERYMAPFEATURES supports selection set persistence.
     317
     318Such changes however, are not within the scope of this RFC.
